To all 107mm itpmay concern Be it known that I, O'rio Pniniiii.iNN, acitizen of the Republic of Switzerland, and

i a resident of Groton, county ot' Tompkins,

and State of New York, have invented certain new and useful lmprovementsin TypelvVriting Machines, of which the jfollowing is a full, clear, andexact description.

This invention relates more particularly to mechanism for vibrating` aribbon transversely of a platen to cover and uncover the print-ing pointot visible or front strike typewritiiig machines.

One of the principal objects oi the invention is to provide simple andetlicient means which is adapted to positively move the ribbon topresent di'lerent lields or zones of different colors to the printingipoint, or which is so arranged that the said ribbon may be made toremain inactive in order that stencils ina;7 be made.

Another object ot the invention is to provide mechanism which isparticularl)v adapted for that type of machines in which the platencarriage is foldable forward in order that the machine may be .moreeoiiipactwhen not in use than when in its normal working position toadapt the machine Vfor transportation or other purposes.

Other objects of the invention are to provide a mechanism which will.positively prevent the ribbon from being;r thrown too high when thekeys are given blows ot' unusual i'oifoe; to provide means whereby thevibrator ina)-v loe brought back to a definite and predeterminedposition and which will positively and rigidly hold the ribbon vibratorwithout 'excessive play no mattei' what its position may be; and toprovide mechanism which is readily accessible and convenient for use.

A further object of the invention is to provide a mechanism which may bepositively adjusted to ditlerent positions so that in one position theribbon vib ator may remain inactive to adapt the machine ,for makingstencils, in the second position will impart a throw to the vibratorsufficient to present one field or zone to the printing point, and in athird position will varyv the extent ot throw ot' the vibrator topresent another field or Zone ofthe ribbon to the printing point.

A t'uither object oit the invention is to provide simple andetlicientmanually operated means for positively indicatingthe field orzone to be presented to the printing point and which always thro theribbon to the same extent during thev same adjustment.

A still further object ot the invention is to provide simple meanscomprising a coni-` parativelv tew parts which `may be 'readily l madeand assembled. and to provide means Specification of Letters Patent.Patgnted DQ-(L 15" 1g) 1 i whereby the vibrator when moved will bejiositively returned always to its normal po sitioii below the printing`point. f

W'th these and other objects Vin view, the invention will be hereinaftermore partira lai-l)1 described with reference to the accompan'vingrlrawin sj'iecil'ii'fation, and will then be pointed out in the claims:it the end of the description.

`which form a part ot this ln the drawings, Figure l is a fralefmen-`tary front elevation of dthe upper portion oi-` a typewriting` machineshowing in front eleration one form of the invention applied. i

bon vibrator remains inactive in yorder that stencils iiia \Y be made.Fig. et is a fragmentary view showing the parts adjusted in order thatone field bt the ribbon, as blaclfor ti ral section taken on the lineVII-VII of f i Fia. 6.

more particularly to a machine in which the carriage and platen aretolded forward or otherwise capable ot' being moved into coinpactrelation to another part of the machine when not Vin use, it will beunderstood that While l show the invention as applied fion the inventionmay be also 'applied-to typewritingand similar machines of various Ykinds and constructions. j

The frame l has a rear plate portion l1 and sides l. Supported by thesides l2 are a.' plurality of rods 13 spaced apart and arranged inparallel relation, and from each rod lis suspended a plurality cikey-levers tt, `Each key-,lever is held inits normal positonf. by aspring 15, one end oi' which is astened to one of .the key-levers andthe Othrend toa transversely extending bar or .same to one. 'of.thetype-bars, not shown, in

plete 16; Each key-lever is provided `with the tnsual keyv atl one endandhas its inner end' provided with -means t6 connect the the 'usualway. `A universal bar 17 extends over the key-levers and thisuniversalbar' has'arms'lS which are pivotally connected at 19l to thearms 20 of'bell-crank levers 21.

There are two bell-crank levers pivoted to' opposite sides of themachine and each bell- Y crank lever has an end 9.2 which is adapted toenter la vertically arranged slot invertical arms 2l of a rocking traine25. These arms Qi are connected at their upperl ends by a transverse baror plate "26' which may be 'formed integral with the arms 2l, said armsbeing hell to a transversely extending rod 2. As each key-lever isdepressed, the imi- Vversal bar will rock the bell-crank levers en theirpivots, vand by reason of the connection of the bell-crank levers withthe rocking frame 25, the latter with the barf'QG will be rocked backand 4forth with the: 1novement or'l eachkey-lever.

' 3T projecting upward in front of the platen .The rod 27 maybeconnectedgto one or more arms 2S which are held to a rod 29, andconnected also to the rods are vertically disposed slides, notI shown,which move in' bearings' 29?" located at the rear corners of themachine, and said posts or slides are-coin nectedito one member of a.toldable or twopart support 30. The'parts of thefoldablc support arepivoted together, at 315 and to the 'foldable member of .the support isheld ay carriage bed 32 along which the carriage 33 is adapted totravel. the platen 3l mounted thereon and said platen and carriage aswell as' the bed 32 Bef This bracket 35 supports the'ribbon v1- AThecarriage has l the stops brator 39. The vibrator 39 isisubstantially the;torm of .a-bell-crank lever land has a4 horizontally extending yarm 40which lies .substantially parallel with the axis 'of the Ontheouter'end' of the'vibrator arm 'isa subplaten when in its normalposition.

stantially shaped loop t1 through which the ribbon may be threadedand bywhichl the ribbon may be moved 'to and from the' printing point as theAvibrator is'operated. The vibrator has anupwardly extending portion 42;which is pivoted 'by a. screw 43 or otherwise to the upper end ofthearm.

37 of the bracket 35, andlsaid -vibrator has a downwardly 'extending armt: which is adapted to entera slot '45 'in ai guide bracket or member46. This bracket 'or member 4:6

is secured to the horizontal portion of the' bracket 35 under the sameand has its slot' l '-l. arranged transversely of the machine and servesto hold and guide the vibrator against rward or backward movementduringthe vibration of the ribbon. A springe? has' one end fastened to avlugt8 on the vibrator and its other end fastened to the' `guide plate ormember 45 and said spring is preferably a light one, and while it tendsto restore the ribbon .vibratorto its normal position, it is.

primarily intended to hold the ribbon `vi brator in its normal positionvwhen the carriage andplatenare moved to a foldedv position. i

To operate the ribbon vibrator and to imvibrator to remain inactive,variousl means may be employed. As one means, I provide an actuatingdevice or member 49. This member 49 is in the Aform ot'a lever having ainger'portion 50 at one end by which the said lever may bemanu-'allyoperated,I the said finger portion being formed as a part ofthe lever and extending vertically to adapt the jsame to be more readilygrasped to movethe lever. This lever is pivoted on4v fa shoulder screw5l, 'whichlatter may-be secured to the rocking bar or plate` 26 of therocking frame 25. rI'he lever or device 49 is pivotally supported' onabracket or` plate`52, the latter being securely held toy the rocking bar26 and is provided 4with proje'ctians 53 and 5st, which form spaces inwhich the body part 56 of the lever is adapted to be movably held,sothat by shifting the lever on its pivot', the said 'leverv may be`trictionally'held against movement in any one of three adjustments'.The plate part various throws thereto or topermit the or bracket 5'? maybe of steel or spring Ametal -V to yield to the movement of' the leverand may have stops 57 and 5S located at oppo' site. edges 'of said plateserving to'limit the lateral movement of the lever 49 about. said plateorbracket. The stops 53 and 5l withl 57 and form three -spaces fora likenumber of adjustments of the lever 49,- T he stop- 53 may be 'higherthan the stop 54.

tbe sir. niet the slot G3 ,zot as Canis sind @ense the arm fl of thevibrator to along tbe saine and thereby shirt the pivot and forse 'he.riboon to point dni-ing tbe movement they rocking' ber in. onedirection, and. will positively. restore the ribbon to its normalporation on the return movement of said bar. A further adjustment ot'the lever if) to the position shown in Fig. 5 will increase 70 theangular relation ot' thoslot 63 with re;- speet to tbe slot V and as therocking bar 26 is operated' by the keys, as here'inbefore described, thesides Gil will impart a greater throw to the vibrator and consequentlyto the ribbon, thus presenting a ditl'erent field or zone of the ribbonto the printing point, and on the return movement of the rocking bar 26will positively restore the ribbo-n vibretor again to its normalposition, though, it will be understood that instead of the threepositions mentioned, the lever may be adjusted to any intermediateposition to 'utilize ythe entlre surface of lthe ribbon 'Where it is ofa single color instead of baving a plurality of colors thereon. By thismeans, tbe vibrator is positively held to move parallel with the face ofthe platen and transversely thereof and against any swinging movementexcept in a' verticaldirect-ion, and said ribbon vibrator is rigidlyheld by reason of the cooperating slotted members in suoli a way that itWill not move to a greater degree when unusually hard .blows are givento the keys than would bethe cese with the ordinary blow, as the arm 44-ot the said vibrator is positively though siidingly held-during itsvibratorymovement, both iirpresenting the ribbon to the 'printingpointand in restoring the same lo@ to its normal position below theprinting point,

l/Vhere a. biclirolne ribbon is'used, the lever in ouch case lmay-havebut three adjustments as shown, one for steneiling purposes in which thevibrator remains inactive, e second for one color or field of theribbon, es black, and a third for a difl'erent field of the ribbon asred. The plate 52 in such ease may be provided with three depressions11g to receive disks or peper or other material, one for steneilingindicated by letter S, a second, the letter B indicating black, and thethird the letter .li indicating rel'htliougli this srrengeinent may beelninfged at will "ind the charactersi lil ewisechanged and the letterformed on or hold to the plate 52 in any desired Way. The lever 49 bosan open-| 65 which is adapted to register with either of the letters andserve as 'indicating ineens so that the operator .may quickly determinowhich field ot' the ribbonis being used or whether or not the ribbon .isbeing operated at all in ease theniaohine .is being used for the purposeot' making stencils.v

it will be Vevident that by reason 'of the slot 63` oi the lever 4.9that theplaten car-,l ringe :Hifi support muy be shifted vertically z toadept the type heads bave o plurality ol characters thereon in the usualWay, that its folding movement of the carriage,`may be Withdrawn fromthe' lever, and on' restoring the carriage to its normal Workingposition,

, the saidarmiorthe lever may be made to again enter the slot l65?. ofthe lever 49 to be operated in the mannen already described.

The lever or actuating member 49 remains in its normal Working positionand always in cooperation 'with the key-actuated means 4as the saidlever is-supported on the rocking frame which may serve also as a. meansfor actuating a part of the escapement mecha-- IllSl'll. V

The invention will. be readily understood from the foregoing descriptionwhen taken in connection with the accompanying drawings. lt .will beseen that whenany one of the keys is operated, the universal bar will bethereby operated and through it and the bell-crank levers 20, therocking frame 25 with its transversebar 26 will be moved back and forth,and owing 4to the lever being supported' on said bar it-Will rocktherewith. It' the lever is in the position shown in Fig. 3, thevibrator elOWill remain inactive owing to the position of the slots 63,and if the lever i9 is moved to the position shown in Fig. 4, the4 blackfield of the ribbon will be presented to the printing point, While onfarther movement of the lever as indicated'in Fig. 5,' the red eld ofthe ribbon vvill be presented to the printing point.

IFrom the foregoing, it will be seen that simple and eiiicient mechanismis provided for vibrating the ribbon tocause the same to cover oruncover the printing point; that said mechanism is particularly adaptedfor typevvriting machines in which the carriage and bed is foldaloleint-o compact relation to another part of the machine; that saidVmechanism is so constructed thatthe vibrator forming a part thereofwill be positively actuated both to move the ribbon to cover theprinting point and to restore the ribbon below the printing point; thatsimple means isprovided whereby the device Without any change Whateveris adapted for stenciling purposes; and that said mechanism is simple inconstruction and has very Simple means for adjustment.
